Advise on where to put expansion joints in the floor

[Crose]

Hello to everyone on the buildhub, I am enjoying reading various articles on this site.

I am in the process of self building a new property and would welcome some advise on where to put expansion joints in the floor.

It will be block and beam floor, 1200 guage dpm, 150mm insulation. 300 guage dpm, underfloor heating, 65mm cement based screed and finally floor tiles to finish.

I have attached the ground floor plan for room sizes.

 

Best Regards

All doorways will need an Expansion joint and keep the tiles at least 10 mil away from the perimeter
